Optimalisasi Kombinasi Biochar dan Pupuk Kotoran Ayam Terhadap Morfologis Bawang Putih (Allium sativum L.) di Tanah Alluvial
Isi Artikel Utama
Abstrak
Garlic (Allium sativum L.) plays a strategic role as a food and health ingredient for the Indonesian people, but the high gap between national production and domestic demand requires efforts to expand agriculture, particularly on potential alluvial land in West Kalimantan. This study aims to evaluate and determine the optimal combination dose of biochar and chicken manure fertiliser on garlic growth parameters and yield on alluvial soil. This study was conducted in South Pontianak District, Pontianak City. The research method was a Complete Randomised Design (CRD) Factorial. The first factor was the biochar dosage (5, 10 and 15 tonnes/ha) and the second factor was the chicken manure dosage (10, 20 and 30 tonnes/ha), resulting in 9 treatment combinations, namely b1p1, b1p2, b1p3, b2p1, b2p2, b2p3, b3p1, b3p2, and b3p3. The combination of biochar and chicken manure had a significant effect on the morphology (bulb diameter and plant height) of garlic in alluvial soil. Among the various variations, the b2p3 treatment (10 tonnes/ha of biochar and 30 tonnes/ha of chicken manure fertiliser) was identified as the most effective dose for optimising plant growth beyond the achievements of other dose combinations.
